TRUNK-FASTENER.

Specification of Letters Patent.

Application lec'l August 11, 1909.

seriai No. 512,291.

To all 'whom it may concern:

Be it known that I, CHARLES Drrrumu, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Trunk-Fasteners, of which the followingis a specification.

This invention relates to' an improved trunk fastener.

The object of the invention is to provide a fastener carried by atrunk-lid and that shall have a pivoted tongue controlled by a lockdevice of improved construction.

The invention is shown in the accompanying drawing in which,

Figure 1 is a front view of the complete device. Fig. 2 is a verticalsection of the device on the line 22 of Fig. 1. Fig. 3 is a view of thedevice as seen from the rear side-the side which is in contact with thetrunk. Fig. 4 is a front view of that part of the device that isintended to be attached to the trunk-lid. Fig. 5 is a horizontalcrosssection taken on the line 5-5 of Fig. 1. Fig. 6 is a verticalsection on the line 6 6 of Fig. 1. Fig. 7 is a top view of the catch orcrossbar that is secured to the box-part of the trunk. Fig. 8 showsperspective views of the tnrnbolt parts.

The numeral, 1, indicates the front wall of the box-part of a trunk. Theframe, 3, which includes the lifter and lock-part of the device issecured to the trunk-lid, 1, and the catch part, 4, of the device issecured to the box-part, 2, of the trunk.

The frame, 3, has fourv holes, 5, for nails, rivets or bolts by whichthe case is secured to the trunk-lid. The frame has a curved oval topand two depending parallel walls, (3, G, which are exposed at the frontpart and a suitable hole or bearing, indicated at the short brokenlines, 7, is in each of said walls. A latch, 8, has position betweensaid two walls, G, and at each side the latch has a laterally-projectingpivot in each hole, 7, whereby the latch can tilt. This latch has at itsupper end a linger' plate, 9, which has position within the top of theframe, 3, and at its lower end the latch has a hook, 10, which engageswith or takes below a crossbar, 11, on the catch, 4, secured to thetrunkboX. The frame, 3, also has two downwardpointing lues, 12, one atthe side of each vertical wall), 6. These lugs enter sockets, 13, whichare formed in a familiar way on the catch device, 4. The catch has threeholes,

14, for nails, rivets or bolts by which it is secured to the trunk-box.

A spring, 15, is so arranged with relation to the latch, 8, that itserves to keep the hook, 10, engaged with the crossbar, 11. One end ofthe spring, 15, is held by a slot, 16, ,in a cross-bar or plate, 17,whose ends are securely fixed in twoI vertical slots, 18. One of thesevertical slots is in each of the walls, G, on the frame, see Figs. 2, 3,5 and 6. The position and action of the spring, 15, will be understoodby reference to Figs. 2 and 3.

The improved lock-device to hold the latch when locked will now bedescribed. Its construction is as follows-The cross-bar, 17, has at itscenter a locking slot, 19, and a turn-bolt has its T-head, 20, enteredthrough said slot; when the bolt is turned so that the T-hcad iscrosswise of the slot, as seen in Fig. 3, the latch, 8, can not tilt,and its hook, 10, will remain engaged with the cross-bar. But when aquarter turn is given the said bolt the long part of the T-head, 20,will be in alinement with said slot, 19, and then the latch may betilted to disengage the hook, 10, from the cross-bar.

A disk, 21, has four radial slots, 2.2, with two of which thc prongs,Q3, on the turn-bolt engage. This disk, 2,1, serves as alooselyconnected head for a turnbolt. In Fig. 8 the turn-bolt and thedisk with radial slots are shown disconnected, but it will readily beunderstood how the two prongs, 23, will fit into two of the slots, Q2.Figs. 2 and 5, also assist to show this.

The latch, 8, has on its front face a circular cavity, 24, whose outercircular edge is slightly undercut below the front face, as seen in Fig.5 and a similar hole, 25, in said cavity opens through the latch. Theturnbolt is placed in the said cavity, the T-head part being passedentirely through the circular hole, 9.5, and the two prongs, 23, restupon the bottom or at the front side of said cavity; the disk, Q1, isthen placed in the cavity and two of its radial slots, 22, are caused toengage with the said two prongs, 23, of the turn-bolt.

An outer disk, 26, covers the slotted disk, 21, and the rim-edge of saidouter disk fits within the circular cavity, 24, and is free to bc turnedbut is confined therein by the ovcrlappinocircular edge of said cavity.This outer disk, 2G, has a central slot, 27, which exposes the twounoccupied radial slots, 22, of the disk, 21. 'lhe other' two slots insaid disk being occupied by the two prongs, 23, of the turn-bolt, 20, asalready explained.

A suitable key (not shown) would comprise a metal bar ust wide enough topermit its end to enter the central slot, 27, in the outer disk, 26; theend of such bar should have two lparallel prongs separated by a spacebetween them. It will be understood such a key may have its two-prongedend entered in the slot, 27 and said prongs will engage the twounoccupied radial slots, 22, of the disk, Q1, and a quarter-turn givento said outer disk, Q6, will also turn the bolt, 20, which has a T-head,and thereby lock the latch, 8, toprevent it from tilting, or unlock itto perm-it lit to tilt,

Having thus described my invention what I claim and desire to secure byLetters Paitent is,-

l. The improved trunk lock comprising-the metal frame 'to be secured tothe trunk-lid and rhaving an -oval top provided with two separate,yexposed depending parallel walls each lhaving `a vertical slot, 18; alatch, 8,V wholly exposed and pivoted between said two walls; a bar, 17,crossing the space between said two walls and the ends of said bar fixedin said vertical slots; a spring, 15, having one end held by saidcross-bar and the other endpressing the latch and a catch to be securedto the trunk-'box and with which said latch engages.

2. The improved trunk lock comprising the metal frame to be secured tothe trunk-lid and having an oval top provided with two separate, exposeddepending parallel walls; a bar crossing the space between said twowalls and the ends of said bar 'fixed to the latter and the center ofthe cross-bar provided with a locking slot, 19; a latch, 8, whollyexposed and pivoted between said two parallel walls and said latchhavinga turn-bolt provided with a T-head that -engages the said lockingslot in the cross-bar, and a catch to be secured to the trunk-box andwith which said latch engages.

n testimony whereof I aiix my signature in presence of two witnesses. K
